ChartDroid is an Intent-based "library application" for static chart and graph generation on Android. It can graph/plot/display numerical data in many representations. As a developer, you need only to have your users install the library, then implement a Content Provider according to this simple specification.

ChartDroid is consistent with the "Unix toolkit" philosophy of building small, interoperable tools. Some developers may prefer to import graphing libraries (.jars) into their project; for that they should look elsewhere. Having ChartDroid exist as an independent application conserves storage space and eliminates redundant code. A minimal example of using ChartDroid with a Content Provider is available.
